Using sleep study data to predict airway collapse in sleep apnea patients

Prediction of Drug-Induced Sleep Endoscopy Outcome From Baseline Diagnostic Data Including Polysomnography

Observational University Hospital, Antwerp · NCT05267808

This study is trying to see if sleep study data can help predict where the airway collapses in people with sleep apnea to improve their treatment.

What this trial studies

This observational study aims to develop predictive models for the site of airway collapse in patients with obstructive sleep apnea (OSA) using baseline polysomnography data. It will involve 1000 patients who have undergone a recent polysomnographic study and will receive drug-induced sleep endoscopy (DISE) as part of their standard care. The study will analyze airflow shape patterns from polysomnography to correlate with DISE results, ultimately creating models to identify the site, pattern, and degree of upper airway collapse. The first phase will validate a preliminary model in 300 patients to assess its predictive accuracy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with obstructive sleep apnea who are eligible for drug-induced sleep endoscopy.

Not a fit: Patients with central sleep apnea, unstable clinical status, or those with certain psychiatric or medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of diagnosing and treating obstructive sleep apnea by providing critical information on airway collapse patterns.

How similar studies have performed: Preliminary analyses in previous research have shown promise in using airflow patterns to predict airway collapse, indicating potential for success in this approach.
